Gov. Jay Inslee will cut the ribbon today on a new grid-scale battery manufactured by UniEnergy Technologies based on Pacific Northwest National Laboratory technology.
Inslee and the Washington State Department of Commerce also will announce new smart grid grants at the event at UniEnergy in Mukilteo. The grants from Inslee's Clean Energy Fund are intended to help utilities integrate power generated from intermittent renewable sources, such as wind and solar, into the electrical grid.
Pat Hoffman, the assistant secretary for the U.S. Department of Energy, is scheduled to attend.
PNNL researchers in Richland have developed advanced batteries made with "redox flow" technology to store large amounts of renewable energy and provide greater stability to the energy grid.
